HDD usage at 99 %

Hi there, im using 1.3.551.38 (Stable channel) (64-Bit) on Win10. Since yesterday i got a weird problem. my vivaldi is always at 99 % hdd usage, when i take a look at my task manager (see screenshot). doesnt matter how many sides i opened, its always at 99 %. any advice? Turri sry for my english, im not a native speaker ;)

Thx TbGbe, that fixed the problem. it seems that uBlockOrigin is causing the problem. after installing it, the usage got up again. i deactivated the extension now and everything is fine. someone else using uBlock with the same setup as mine and got problems?
